Anemonoides nemorosa, commonly called wood anemone, is a rhizomatous spring ephemeral native to European woodlands. Rising 10–25 cm tall, it produces a single, starry flower per stem, typically with 6–7 white tepals that may blush pink or lilac in cool weather, and a boss of yellow stamens. Trifoliate, deeply lobed leaves form a whorl beneath the flower. Plants spread slowly by brittle, shallow rhizomes, often forming broad drifts that carpet forest floors in early to mid‑spring before canopy leaf‑out. After flowering and setting seed, the foliage senesces as temperatures rise and shade deepens, leading to summer dormancy. It prefers humus‑rich, well‑drained soils that remain evenly moist in spring. Ecologically, wood anemone provides early nectar and pollen for bees and hoverflies. In gardens, it excels under deciduous shrubs and trees, naturalizing in lightly managed, leaf‑littered beds. Handle with care: all parts contain protoanemonin and can irritate skin or cause gastrointestinal upset if ingested.

How to care for Wood anemone
Water
Maintain consistently moist, never waterlogged soil during active growth (late winter through late spring). Water deeply once the top 2–3 cm of soil begins to dry, then allow slight drying between sessions. Mulch with leaf mold to reduce evaporation and keep roots cool. After flowering, as foliage yellows and dormancy begins, gradually reduce watering; established clumps in the ground typically need none in summer. In containers, give just enough water during dormancy to prevent the medium from becoming bone‑dry.
Light
Provide partial shade to dappled light, ideally under deciduous trees or shrubs. In late winter and early spring, plants benefit from several hours of sun before canopy leaf‑out, which boosts flowering. As the season advances, increasing shade helps keep soils cool and moist. Avoid full, unfiltered midday sun, which can scorch foliage and shorten bloom, and deep, continuous shade, which reduces flowering. East or north exposure, or woodland understory light, is ideal.
Nutrients
Wood anemone is adapted to low‑fertility woodland soils. Instead of conventional fertilizer, top‑dress annually in autumn with 2–5 cm of leaf mold or fine compost to mimic natural leaf litter and feed soil life. Avoid high‑nitrogen or manure‑rich feeds, which can encourage soft growth and reduce flowering. In containers, mix slow‑release, balanced organic fertilizer at half strength in early spring. Maintain a mulch layer to conserve moisture and buffer nutrients during active growth.
Temperature
Hardy in USDA Zones 4–8. Plants grow best in cool springs: daytime 5–18°C, nights near freezing are tolerated. Fully dormant rhizomes withstand severe winter cold (to about −30°C) under insulating soil and mulch. Summer heat is acceptable if soils do not bake; prolonged temperatures above 28–30°C with drought can stress or shrink clumps. Provide a mulch layer to moderate temperature swings, and avoid hot, reflective sites, especially in containers where roots warm rapidly.
